Deep-sea Fauna of European Seas: Echinoidea
IdentificationRemarks: Two Atlantic species of Tromikosoma are very closely related and may perhaps ultimately prove to be identical. Very little material is known on these two species. Therefore it is difficult to tell exactly differences between the two species
<http://www.opengis.net/def/crs/EPSG/0/4326> POINT (63.1 -56)
IdentificationRemarks: Three varieties were distinguished by Mortensen (1935): the typical form in the North and East Atlantic, P. placenta sigsbei in the West Atlantic and P. placenta africana in the South Africa area
IdentificationRemarks: the subspecies H.expergitus gibbosus occurs in the West Pacific from Japan to New Zealand

IdentificationRemarks: According to Markov (1988b), the species S. profundi consists of 6 subspecies: S.profundi profundi, S. profundi miliaris Agassiz,1898, S. profundi indica Mortensen, 1939, S. profundi brevispina Markov, 1988, S. profundi intermedius Markov, 1988, S. profun
IdentificationRemarks: Mironov, Sagaidachny (1984) distinguished seven morphological varieties of E. scaber, among them E. scaber macrostomus which is most similar to E. scaber scaber from the Indo-West Pacific. E. scaber macrostomus differs slightly from the typical form by a
IdentificationRemarks: It seems doubtful that there is any real distinction between the Atlantic species A. bellidifera and the Indo-Pacific species A. ovata (Mortensen, 1950; Mironov, 1975)
IdentificationRemarks: As for the genus. The fragments of Calymne relicta obtained by “Challenger” are labelled: “Fayal. 2650 fms” (Agassiz, 1881). According to H.L. Clark (1925), “the narrative and summary of results of the Challenger show that the true locality was not very

IdentificationRemarks: C. cidaris is very closely related to the west Atlantic C. rugosa (H.L. Clark, 1907) and C. abyssicola (Agassiz, 1869);Koehler (1909)perhaps erroneously indicated station 1306, “Princesse Alice” located at the depth of 4275 m
IdentificationRemarks: The record of T. uranus in the Indian Ocean (3345 m) is questionable, because thespecimens are juveniles (Mortensen, 1939)

IdentificationRemarks: S. grimaldii agrees very closely with S. antillense Mortensen, 1934 from the west Atlantic in every aspect except for the fact that the test of S.antillense is looking more bare
<http://www.opengis.net/def/crs/EPSG/0/4326> POINT (35.72 -8.27)
IdentificationRemarks: David, Sibuet(1985) recorded the species at depths up to 4700 min the Bay of Biscay
